Application of waterproof sealing materials for underground bottom plate pile head
This paper studies the setting time,application effect and compatibility with polymer waterproof sealing material pre-laid on the large surface of the underground bottom plate pile head using different edge pressing mortars and sealing materials.The results show that the quick-drying impermeable high-strength waterproof mortar as the pressing mortar for pile head coil and the silane modified polyether waterproof coating as the sealing material can effectively solve the waterproof sealing problem of pile head.The research results can provide a material combination scheme for pile head waterproof sealing for the project of underground bottom plate construction using pre-laid polymer waterproof coil,and solve the problem of pile head leakage.
